There is strong global evidence that early childhood development provides a solid foundation for good health, growth, and success in education. Programs focusing on early learning promote awareness of child development and lead to higher enrolments and less repetition, especially among the children from poor families. Transition from home to early child development center and early child development center to primary school are critical moments for young children and for those children who have the opportunity hold a highly positive implication for them (Woodhead, M. & Moss, P., 2007). The positive impact of early childhood development on participation and achievement in primary school and beyond is well documented in many studies (Arnold, 2007; Mustard, 2005; Young, 2002, 2007).

The methodology of this review consists mainly of desk study of relevant materials. The review of academic research, policy papers, documents and reports, links and data on program and practices is the principal source of this review.
